The circuit I designed is *very simple*. You program an EPROM with several
different game programs, and the circuit switches through the different
pages by setting the upper address bits. It doesn't switch any other kind of
hardware in and out. Sorry if I got your hopes up.

I'm going to post the schematic here on the list as a PDF. For a more
permanent home, I should probably add it to someone's Pac-Man page, since
Pac-Man is probably the game with the most ROM-only game swaps.

More to come soon...
